The chance of recurrence after stenting for heart attack is generally 10% to 30%, but the exact chance of recurrence depends on the severity of the patient’s condition and the effectiveness of his or her own care. If the patient’s condition was serious before, and the late care is not in place, it may recur at any time. If the patient is treated in a timely manner and has a good prognosis and no symptoms in the short term, the chance of recurrence is low. After an infarction, if there is myocardial damage, heart failure and other complications, the infarction can recur at any time, and shock may occur in severe cases. Stenting improves the blood supply to the heart muscle and reduces the chance of myocardial infarction. After cardiac stent surgery, you need to pay attention to follow the doctor’s instructions to take lipid-lowering and anticoagulant drugs, to avoid the occurrence of various complications, and to reduce the chances of recurrence. After stent surgery, you should pay attention to rest, take medication regularly, and go to the hospital in time if other symptoms occur.
